What reason is coughing to still have blood sputum to come out when having a meal

The patient coughs and has bloody sputum as soon as he eats. It is considered that the patient is infected with bacteria, viruses and other pathogenic bacteria, causing upper respiratory tract infection, pneumonia or bronchitis and other diseases. When the patient coughs more violently, it will cause blood vessels to rupture and bleed, thus causing cough, hemoptysis and other symptoms.
